title: Optogenetics, visual prosthesis and electrostimulation for retinal dystrophies.
abstract: OBJECTIVE
  Outer retinal degenerations such as retinitis pigmentosa can cause profound vision loss. Various treatment strategies are being pursued to potentially restore functional vision in these patients.
  
  
  RESULTS
  Advances in retinal prostheses have restored some vision in patients previously blind from retinitis pigmentosa. Optogenetics is another area that shows promise for restoration of vision. Transcorneal electrostimulation shows some efficacy to treat these patients as well.
  
  
  CONCLUSIONS
  We review recent advances in optogenetics, visual prosthesis and electrostimulation to treat outer retinal degenerations.
